Two pairs of retaining windows 156 are respectively defined in the first wall 15 on opposite sides of the corresponding SCA2 receptacle 13, 14. The SCA2 receptacles 13, 14 which can be replaced by other electrical connection devices serve to electrically engage the transceivers received in the guide rails 3, 4. In addition, two pairs of opposing recesses 158 are respectively defined in the first wall 15 and each vertically adjacent to the corresponding retaining window 156. A pair of screws 154 is formed in the first wall 15 for fastening the spacer 2 (depicted in FIG. 2) to the first wall 15.

Turning to FIGS. 2 and 3, a first portion 181 of a flexible printed circuit (FPC) 18 is affixed to the first wall 15, for connection with the SCA2 receptacles thereby electrically connecting the transceivers to the printed circuit board 6. A second portion 184 of the FPC 18 is bent upwardly at the bottom of the raiser 1 with a bending potion 182 being formed and sandwiched between the base 17 and a plate 16 that is fastened to the base 17 by screws 172.

Referring to FIGS. 2 and 5, the lower rail guide 4 comprises an upper cover 41 and a frame 42 covered by the upper cover 41. The frame 42 comprises a window 43 and two parallel sidewalls 44 extending from the window 43. Opposite to the window 43 of the frame 42, a cross beam (not shown) is formed between the sidewalls 44. Two positioning posts 443 are formed in each sidewall 44, and two supporting posts 441 are formed in each sidewall 44. In addition, a positioning protrusion 444 and a hook 445, opposite to the window 43 of the frame 42, are formed on an end of each sidewall 44. A swivel door (not labeled) is disposed about the window 43.

Similar to the lower guide rail 4, the upper guide rail 3 also comprises an upper cover 31 and a frame 32 covered by the upper cover 31. The frame 32 comprises a window 33, two parallel sidewalls 34 extending from the window 33, and a cross beam (not shown) formed between the two sidewalls 34 and opposite to the window 33 of the frame 32. Two positioning posts 343 are formed on each sidewall 34. In addition, a positioning protrusion 344 and a hook 345, opposite to the window 33 of the frame 32, are formed on an end of each sidewall 34. A swivel door (not labeled) is disposed about the window 33.

Turning to FIGS. 2 and 5, the spacer 2 comprises two parallel side members 21, a cross arm 22 and a front plate 23. A pairs of positioning slots 212 is defined in each side member 21, for receivingly mating with the corresponding positioning posts 443 of the lower guide rail 4 and positioning posts 343 of the upper guide rail 3. The spacer 2 is secured to the raiser 1 by the screws 154 engaging screw holes 232 defined in the front plate 23.

An opening 61 having a first rectangular zone 62 for receiving the lower rail guide 4 therein and a second rectangular zone 63 for receiving the raiser 1 therein is defined in an edge of the printed circuit board 6. Two pairs of holes 612 are defined on opposite sides of the first zone 62 for receiving the corresponding supporting posts 441 of the lower guide rail 4.
